This invention relates to a ventilator construetion for use in motor Vehicles and the like, and more particularly to a ventilator arranged in the hood of an automobile body; V

In conventional practice, where the so-called cowl ventilators are used in motor vehiclesjit has been the custom'to provide a fixed exterior cowl section extending forwardly from the wind shield, such cowl section having an opening formed therein for ventilating purposes and adapted to be closed by means of a movable ventilator closure or cover carried bythe cowl section. In such constructions it has heretofore been necessary, in order to obviate interference with the ventilator structure when the hood sections are raised and lowered, to shorten the hinged hood sections so that they will only extend'forwardly from a point in advance of the cowl and cowl ventilator.

An objectof the pre ent invention is to provide an improved vehicle body and ventilator construction wherein the hood sections may be extended rearwardly to any desired point in ad vance of the windshield and wherein the yentilator may be mounted within the confines of the hood, as a result of which the ventilator closure maybe operated independently of the hood and the *hood raised "and lowered independently of the ventilator. I 4

It is therefore one of the important objects of 'this invention to p'rovide'a ventilator struc-' ture which is mounted on a fixed portion of the vehicle, whichpe'rmits ventilation through the top of the hood, and which is separate from the hood sections so that the hood sections may each be operated without interference from the ventilator. The invention also contemplates an arrangement wherein the ventilator closure is in registration with the opening in the hood when the latter is closed, the ventilator being controlled by a closure which, in its closed position, is located in the plane of the hood opening and, to all appearances, forms a continuation of the hood.

The several objects, advantages and novel features of construction of the invention will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawings, wherein Figure 1 is a fragmentary perspective view of a portion of a motor vehicle, having a ventilator constructed in accordance with my invention;

Figure 2 is a similar view with the hood section partially raised;

Figure 3 is a fragmentary longitudinal sec- (oll s s-.2)

tional elevational view of a motor vehicle showing the ventilator structure; I

' Figure 4 is an enlarged sectional view through 1 the-closure end of the ventilator, and 1 i 'Figure 5 is an enlarged sectional view taken substantiallyon a plane indicated by line 5--5 in Figure 3.

' Referring now moreparticularly to the drawings wherein like reference characters indicate like parts, itwill be noted that there is illustrated fragmentarily, the windshield 10, hood 11, dash-12, and motor 13 of a motor vehicle. In the present embodiment of the invention, herein shown by way of example, the pivoted-sections of the hood 1 1 are extended rearwardly substan-- tially to the windshield, and hence in such case the usualexposed cowl'section is eliminated. A ventilator'is provided and'disposed with a ventilating opening located within the area or confines of the hood at the top thereof, this ventilator including a movable" closure and operatingmechanism therefor carried by or supported from-the dash beneath the'hood. In the present instance the dash 12 is provided with an opening 14 and preferably secured to the dash, in registration with this'opening 14, is a ventilator conduit 15. While any preferred or desired means may be provided for attachingthe conduit to th'e'dash, I-h'ave provided'angle members 16, one flange of each'of which is secured by bolt and slot connections" 17' to the dash,- whereas the other'flange' of each is secured by bolt; and slot connections '18 with the conduit. The slots ex-. te'ndin opposite directionssothat a substantial uninversal adjustment of the conduit with respect to the dash, is possible.

The conduit 15 extends upwardly into registration with an opening 19 in the hood section 11, and it is for the purpose of providing for an alignment of the upper end of the conduit with the opening 19 that the universal mounting aforesaid of the conduit, is provided.

As seen most clearly in Figure 4, the upper end of the conduit 15 is provided with a U-shaped channel member 20 around the periphery thereof, in which a resilient pad or the like 21, is located. The opening 19 in the hood section 11 is provided peripherally thereof with a downwardly extending flange 22 which enters the U-shaped channel 20 in the closed position of the hood section and engages the pad 21 to provide a substantially weatherproof joint.

The ventilating opening through the hood is adapted to be closed by a closure member 23. In the present instance this closure is provided is closed and when the closure 23 is in its-shut position, this latter closure lies in the same general plane as the opening l9 in the hood section and to all appearances forms a continuationof the hood section.

However, the closure 23 may be opened to permit air to flow through the conduit 15 and through the opening 14 of the dash and .thus into the interior of the vehicle. Moreover, the hood section 11 may be opened without interference from the ventilator as the latter is mounted entirely inv dependently thereof.

Obvious modifications may suggest themselves to those skilled in this art and to this end reservation is made to make such changesas may come within the purview of the accompanying claims.

I claim: 1 I

1. In a vehicle body in which the hood extends rearwardly to a point adjacent the windshield, the combination of a movable hood sectionhaving an opening therein, a dash, and a ventilator conduit secured to said dash and extending under said hood section and into registration with said opening when the hood section is closed. v

2. In a vehicle body in which the hood extends rearwardly to a point adjacent the windshield, the combination of a movable hood section having an opening therein, a dash, a ventilator conduit secured to said dash and extending under said hood section into registration with saidopening when the hood section is closed, and means for adjustably securing said conduit to said dash.

3. In a vehicle bodyin which the hood extends rearwardly to a. point adjacent the windshield, the combination of a movable hood section having an opening therein, a dash, a ventilator conduit secured to said dash and extending under said hood section into registration with said opening when the hood section is closed, and a closure for said conduit located in the plane of the hood opening when the hood is in closed position. r

- 4. In a'vehicle body, a dash having a ventilator conduit connected thereto, a hood memberhaving an opening therein registering with the upper end of said conduit, and a closure for said conduit located in the plane of the hood opening when the hood is in closed position.

5. In a vehicle body, a hood member provided with an opening therein, a dash provided with an opening therethrough, a conduit secured to said dash and extending from the opening-therein to the. hood opening, and a closure for said conduit located in the opening of the hood when the latter is-in closed position.

6. In a ventilator structure for automobiles, a pivoted hood section having a ventilating opening, a fixed body frame portion beneath the hood, a ventilator closure carried by said frame portion independently of the hood section for closing said opening, said closure being disposed within the confines of the hood section when closed and the latter adapted to be raised and lowered without interfering with the closure.

7.. In a ventilator for an automobile body having a dash and a pivoted hood section provided with a. ventilating opening at its top, a movable closure supported from said dash and adapted to lie withinysaid opening when the hood section is lowered, said hood section adapted to be raised and lowered independently of the closure. 8.
